ScoringGO / NO-GO
ResultFail = eliminated from testing

Day 1 is the gate. Candidates must pass the ACFT to standard — no waivers, no exceptions. Immediately following, a written examination tests knowledge of warrior tasks, soldier training publications (STPs), and common doctrine.

This day eliminates candidates who are not physically prepared or who failed to study. The written exam covers the full ESB task list — weapons, first aid, communications, CBRN, and more. It is not a memorization test; it requires understanding of procedures.

Candidates who fail either the ACFT or the written exam are dropped immediately and cannot continue to warrior task testing.

Day 1 Events
  • ACFT — all six events to standard
  • Written exam — warrior tasks, STPs, common doctrine
  • No waivers or alternate events accepted
  • Failure on either event = immediate elimination
  • Results posted same day — pass/fail only

Key Events

First AidTCCC, tourniquet, casualty evac
CommunicationsRadio ops, SALUTE reports
DemolitionsCharge prep, firing systems

Warrior task testing is the heart of the ESB and where ~40% of all candidates fail. Over two days, candidates rotate through 30+ individual task lanes covering the full spectrum of soldier skills.

Every lane is graded GO / NO-GO with zero deficiency — one critical step missed and the entire task is a failure. Weapons handling covers the M4, M249, M240B, M18 Claymore, and AT4. First aid lanes test Tactical Combat Casualty Care (TCCC) under pressure.

CBRN procedures, communications, demolitions, and react-to-contact drills round out the testing. There are no second chances — candidates must execute every task to standard on the first attempt.

Warrior Task Lanes
  • Weapons — assemble, disassemble, functions check, immediate action for M4, M249, M240B
  • M18 Claymore mine — emplacement and firing
  • AT4 — prepare to fire, backblast area clear procedures
  • TCCC — tourniquet application, airway management, casualty evacuation
  • CBRN — MOPP gear, mask drills, decontamination, NBC-1 reports
  • Communications — radio operations, SALUTE and MEDEVAC reports
  • Demolitions — non-electric and electric firing systems
Land Navigation — Day & Night
Day 4
Duration1 Day (day & night)
Day Course5km, compass & protractor
Night Course5km, limited visibility
Requirements
EquipmentCompass, protractor, map
No GPSMap and compass only
Pace CountMust know your pace
Terrain Assoc.Primary navigation method

Land navigation accounts for ~20% of all ESB failures. Candidates must complete both a daytime and nighttime course using only a compass, protractor, and 1:50,000 scale map — no GPS, no electronics.

The day course covers approximately 5km with multiple points. Night navigation is the killer — the same distance in limited visibility where terrain association and pace count become critical survival skills. One missed point can end your ESB attempt.

Candidates must plot points accurately, navigate efficiently, and find all required points within the time standard. Terrain association — not just compass bearing — separates those who pass from those who wander.

Land Nav Essentials
  • 5km day course — multiple points, timed
  • 5km night course — limited visibility, no artificial light for navigation
  • Compass and protractor — primary tools
  • Pace count — know yours on flat and rough terrain
  • Terrain association — the most reliable navigation method
  • Map reading — contour lines, grid coordinates, declination
12-Mile Ruck March — The Finisher
Day 5
Distance12 miles
Time StandardUnder 3 hours
Minimum Load35 lbs (dry weight)
Requirements
Pace~15:00 min/mile or faster
WeaponCarried throughout
RunningNot authorized
CompletionEarns the ESB

The 12-mile ruck march is the final event of ESB testing. Candidates who have passed everything else must now complete 12 miles with a 35-pound minimum load (dry weight) in under 3 hours. This is a foot march — running is not authorized.

~12% of candidates who make it to Day 5 fail here. Heat casualties are the primary threat during summer testing windows, where black flag conditions can delay or modify the event. Foot care and ruck march training in the weeks before testing are critical.

Successful completion of the 12-mile ruck march earns the Expert Soldier Badge — the Army's mark of warrior proficiency across all MOS.

Ruck March Tips
  • Train with weight — 35lb minimum, build up gradually
  • Know your pace — 15:00 min/mile keeps you under 3 hours
  • Foot care — break in boots, two-sock system, moleskin
  • Hydrate — especially in summer heat conditions
  • Pack smart — weight high and close to your back
  • Mental toughness — miles 8-12 are where candidates break
Seasons
Winter — Cold Hands, Hard Tasks
Dec – Feb
ESB FrequencyLess common
TemperatureBelow freezing at many sites
Warrior TasksCold hands slow fine motor
Land NavShort daylight hours
Ruck MarchCold-weather layering critical
Biggest ThreatNumb hands on weapons tasks

Winter ESB testing is less common but still conducted at some installations. Cold temperatures create unique challenges — fine motor skills degrade when hands go numb, making weapons assembly and disassembly significantly harder.

Winter Tips
  • Practice warrior tasks with cold hands — wear gloves until the lane starts
  • Layer properly for the ruck — sweat management is critical
  • Short daylight hours affect land nav timing
  • Keep hand warmers available between task lanes
  • Mental toughness — cold adds stress to every event
Spring — Most Popular Testing Window
Mar – May
ESB FrequencyMost popular window
TemperatureComfortable at most sites
Warrior TasksIdeal conditions
Land NavGood visibility, mild weather
Ruck MarchCool mornings, manageable temps
Best ForFirst-time ESB candidates

Spring is the most popular ESB testing window. Comfortable temperatures mean fine motor skills are not degraded by cold, and heat casualties are rare. Most units schedule their primary ESB testing in spring.

Spring Tips
  • Peak competition — largest candidate pools
  • Weather is rarely a factor — focus on tasks
  • Rain is possible — waterproof your packing list
  • Morning land nav can be cool — light layers
  • Best conditions for ruck march performance
Summer — Heat Is the Enemy
Jun – Aug
ESB FrequencyConducted, with heat risk
Temperature90°F+ at southern posts
Heat CasualtiesPeak during ruck march
Black FlagCan delay or modify events
HydrationCritical throughout testing
Biggest ThreatHeat stroke on 12-mile ruck

Summer heat is the primary threat during ESB testing. Heat casualties peak on the 12-mile ruck march, and black flag conditions can delay or modify events. Southern installations are especially brutal — Fort Benning, Fort Hood, and Fort Bragg regularly see 90°F+ during testing.

Summer Tips
  • Heat acclimate for 2+ weeks before testing
  • Hydrate aggressively — water and electrolytes
  • Start ruck march training in heat conditions
  • Know heat casualty signs — for yourself and buddies
  • Black flag protocols — events may start earlier or be modified
Fall — Ideal Conditions, Second Most Popular
Sep – Nov
ESB FrequencySecond most popular
TemperatureCooling, comfortable
Warrior TasksIdeal conditions
Land NavLeaf cover changes terrain
Ruck MarchCool weather, low heat risk
Best ForRetesting after spring/summer

Fall offers ideal testing conditions and is the second most popular ESB window. Cooling temperatures eliminate heat casualty risk while keeping hands warm enough for fine motor warrior tasks. Many units schedule fall testing as a second opportunity.

Fall Tips
  • Ideal ruck march conditions — cool mornings
  • Fallen leaves can obscure land nav features
  • Shorter daylight — night nav starts earlier
  • Good retesting window after spring failures
  • Weather can change rapidly — layer accordingly

Key Context
Voluntary Withdrawal~3%
Weapons lanes are #1 warrior task failureMost drops
Night land nav accounts for most nav failures~65% of nav
Summer ruck march has highest heat casualtiesPeak risk

Key Takeaway: Warrior tasks are the #1 killer. With 30+ lanes graded GO/NO-GO at zero deficiency, you must execute every step of every task perfectly. Rehearse until the procedures are automatic — there is no room for thinking on the lane.
